Abstract

The invention discloses a sound-proof material, a preparation method and an application of the sound-proof material. The sound-proof material is prepared from the following raw materials: graphene, polyethene, chloroprene rubber, polyoxypropylene triol, caprylic / capric triglyceride, a methacrylate polymer, brominated paraffin, a quartz glass fiber, maleic anhydride, an ethylene-ethyl acrylate copolymer, acetic acid ethenyl ester copolymer emulsion, trisopropanolamine, an adhesive, a dispersing agent, a tackifier, a cross-linking agent, a catalyst, a plasticizer, a flexibilizer, a foaming agent, a foaming regulator, a foam stabilizer, a curing agent, a degradation agent and a stabilizer. The sound-proof material is prepared by the steps of mixing, extruding and the like. The sound-proof material is applied to 3D (three dimensional) printing. The material is degradable, can be degraded completely after 267-283 days, and a sound reduction index is 25.36-29.51 dB which shows that the material has a good sound-proof effect.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of sound-insulating material preparation, and in particular relates to a sound-insulating material, a preparation method and an application thereof. [0003] 【Background technique】 [0004] Foam material is also called porous material. It is made of resin as the main raw material and has countless micropores inside. It has the functions of light weight, heat insulation, shock resistance and corrosion resistance. It is widely used as packaging materials and car and ship shells. [0005] In 2004, Geim and Novoselov of the University of Manchester in the United Kingdom obtained independent two-dimensional graphene (Gra-phene, GN) crystals by stripping highly oriented graphite through tape, and graphene has become a research hotspot in the field of materials science. one. Graphene is actually a single atomic layer of graphite, which has a unique two-dimensional structure and excellent mechanical, thermo...
